DETAILED DESCRIPTION

As described above, in a cloud computing environment that supports multiple tenants, software applications can be associated with lifecycle activities that determine a runtime behavior or how the software applications operate.

However, software application bugs or other technical issues may arise from time to time that are associated either with the cloud environment itself, or with a particular software application. Different tenants may have different requirements as to the behavior of the cloud environment or their software applications, which may in turn necessitate a version update to the cloud environment. However, such a change of behavior may not be applicable to all tenants, but may instead be required only by certain tenants.

Preparing a version update to a cloud environment or cloud platform generally takes several days, while tenants (customer) wait for that update to be available. As an alternative, a tenant's platform instance can be patched to provide the change in functionality. However, patching generally requires downtime for that platform instance, and may not be readily duplicated in other platform instances or platform versions. Some cloud environments, such as Oracle Cloud, support the use of feature flags that allow various features to be provided within a cloud platform, but not made active unless turned on. However, such features still need to be pre-configured or pre-installed into the platform, for example through a version update or patching, so that they can be later activated, and as such cannot be provided dynamically.

In accordance with an embodiment, described herein is a system and method for behavior injection in a cloud computing platform (cloud platform) or software application, including the use of injection points to modify the operation or behavior of a tenant platform environment. An injection service enables a cloud platform provider to configure software code/behaviors to be injected into cloud platform modules or other components associated with tenants, including mapping, for a tenant-specific globally unique identifier (GUID) associated with a lifecycle activity injection point, a behavior including a platform code or process and metadata that can be used to inject and modify operation of a corresponding module. The described approach enables a cloud platform to expose behavioral aspects of the cloud platform or a software application executing therein, so that they can be controlled or modified in a dynamic manner, from outside of the cloud platform.

In accordance with an embodiment, a technical advantage of the described systems and methods includes that the described approach enables a cloud platform to expose behavioral aspects of the cloud platform or a software application executing therein, so that they can be controlled or modified in a dynamic manner, from outside of the cloud platform.

Cloud Platforms

FIG. 1 illustrates a system for behavior injection in cloud computing platforms or software applications, in accordance with an embodiment.

As illustrated in FIG. 1, in accordance with an embodiment, a cloud computing environment (cloud environment) 100, such as for example an integration cloud, operating at one or more computers that includes a computer hardware (e.g., processor, memory) 102, can be used to provide a cloud computing platform (cloud platform) 104.

In accordance with an embodiment, examples of such a cloud environment and cloud platform can include Oracle Cloud and Oracle Integration Cloud (OIC) respectively. In accordance with various embodiments, the teachings described herein can also be used with other types of cloud environment or cloud platform, including, for example, other types of platform-as-a-service (PaaS) cloud environments or cloud platforms.

In accordance with an embodiment, each of a plurality of tenants of the cloud environment, for example a first tenant A, can be associated with a tenant platform environment 110, for use with the tenant's computing environment 112, and with one or more cloud software application(s) 114, and/or integration(s) 116. For example in accordance with an embodiment, the tenant can access their platform environment from an on-premise computing environment via a cloud environment 130 or other type of network or communication environment.

In accordance with an embodiment, a tenant platform environment can utilize one or more platform modules 140, cloud software applications or services 150, or third-party or other software applications or services 158, provided by the cloud platform. The cloud platform can orchestrate use by the tenant platform environment, or by software applications executing therein, of various lifecycle activities provided within cloud platform as modules (components) A 162, B 164, N 168, as part of a tenant lifecycle 170 associated with those modules.

For example, in accordance with an embodiment, a cloud platform operating as an integration platform can orchestrate various software applications and multiple modules working together, such as, for example, activation, connection test, metadata loading, invoke target endpoint, transformation, request received by an integration, or various other types of modules; and can provide various lifecycle activities performed by these modules. During runtime, the modules can then execute the lifecycle activities to address various use-cases.

In accordance with an embodiment, the various components and processes illustrated in FIG. 1, and as further described herein with regard to various embodiments, can be provided as software or program code executable by a computer system or other type of processing device. For example, in accordance with an embodiment, the components and processes described herein can be provided by a cloud computing system, or by another suitably-programmed computer system.

FIG. 2 further illustrates a system for behavior injection in cloud computing platforms or software applications, in accordance with an embodiment.

As illustrated in FIG. 2, in accordance with an embodiment, each of one or more modules can be associated with one or more injection points or hooks by which to associate a platform code or process. For example, as illustrated in FIG. 2, a first module A can be associated with injection points (A1) 182 and (A2) 183; while a second module B can be associated with an injection points (B1) 184; and a third module C can be associated with injection points (C1) 185, (C2) 186, and (A3) 187; each of which can be used to inject a platform code or process to control or modify operation of the module.

FIG. 3 further illustrates a system for behavior injection in cloud computing platforms or software applications, in accordance with an embodiment.

As illustrated in FIG. 3, in accordance with an embodiment, a second tenant B can be similarly associated with a tenant platform environment 120, for use with the tenant's computing environment 122, and with one or more cloud software application(s) 124, and/or integration(s) 126; and can similarly access their platform environment from an on-premise computing environment via the cloud environment.

However, different tenants may have different requirements as to the behavior of the cloud environment or their software applications; and such behavior may not be applicable to all tenants, but may instead be required only by certain tenants.

In accordance with an embodiment, to address this, injection points associated with various modules can be used inject a platform code or process to modify or control the operation of that module. For example, in an OIC or other cloud platform or cloud environment, such injection points can be used, for example to:

EXAMPLE 1

In an example of invoking a target endpoint, if a target endpoint changes its contract due to technical reasons, then the system can use injection to immediately change the caller's behavior by injecting the change of behavior.

EXAMPLE 2

In another example of regression caused by a feature or bug fix. If the regression is related to the lifecycle activities, then injection can be used to fix the issue in runtime until the actual fix is made available by the cloud platform.

EXAMPLE 3

In yet another example, injection is useful for debugging intermittent issues for certain tenants.

Configuration of Injection Points

FIG. 4 further illustrates a system for behavior injection in cloud computing platforms or software applications, in accordance with an embodiment.

As illustrated in FIG. 4, in accordance with an embodiment, each particular tenant can be associated with one or more tenant-specific globally unique identifiers (GUID) associated with lifecycle activity injection points. In the example illustrated in FIG. 4, a first tenant A can be associated with a plurality of tenant-specific GUIDs 200, including a first GUID A 202 that references injection point (A1) in module A; and a second GUID B 204 that references injection point (B1) in module B.

Generally described, in accordance with an embodiment, a tenant-specific GUID can be used to indicate the association of one or more (or all) tenants, with one or more module injection points, for purposes of requesting and receiving platform codes or processes from an injection service, as further described below.

FIG. 5 further illustrates a system for behavior injection in cloud computing platforms or software applications, in accordance with an embodiment.

As illustrated in FIG. 5, in accordance with an embodiment, in this example a second tenant B can be associated with a plurality of tenant-specific GUIDs 210, including a first GUID C 212 that references injection point (A2) in module A; and a second GUID D 214 that references injection point (B1) in module B.

FIG. 6 further illustrates a system for behavior injection in cloud computing platforms or software applications, in accordance with an embodiment.

As illustrated in FIG. 6, in accordance with an embodiment, in this example with a plurality of tenant-specific GUIDs 220, including a first GUID X 222 that references injection point (N2) in module N; and a second GUID Y 224 that references injection point (N2) in module N can be used in associated with both tenants A and B. Using such a GUID that can be matched to multiple tenants, can enable an injected behavior to be associated with those multiple tenants.

As such, each tenant-specific GUID need not necessarily be specific to a single tenant, but can instead be specific to a selection or number of tenants, or indeed to all tenants, depending on how widespread the injection is intended to be employed throughout one or more, or all of the tenants of the cloud environment, as appropriate.

The above examples are provided for purposes of illustration. In accordance with various embodiments, different arrangements of tenant-specific GUIDs and associated with one or more, or all of the tenants of the cloud environment can be used, to address various use cases.

Injection Service

FIG. 7 further illustrates a system for behavior injection in cloud computing platforms or software applications, in accordance with an embodiment.

As illustrated in FIG. 7, in accordance with an embodiment, an injection service 230 can be provided at one or more computers that includes a computer hardware (e.g., processor, memory) 132, and provides an injection service application program interface (API) 234 that enables communication with the injection service.

In accordance with an embodiment, the injection service enables a cloud platform provider to configure (for example, via a configuration file, graphical user interface, or other configuration means) a plurality of software code/behaviors 236 that can be injected into cloud platform modules or other components associated with tenants.

In accordance with an embodiment, the injection service enables mapping, for each of a plurality of tenant-specific GUIDs associated with lifecycle activity injection points, a behavior including a platform code or process and metadata that can be used to inject and modify operation of a corresponding module.

For example, in accordance with an embodiment and the example illustrated in FIG. 7, a first GUID A 202 can be mapped to a platform code or process 240 and a metadata 241 that can be used to inject and modify operation of a corresponding module. A second GUID B 204 can be similarly mapped to a platform code or process 244 and a metadata 245 that can be used to inject and modify operation of a corresponding module. A third GUID C 212 can be similarly mapped to a platform code or process 248 and a metadata 249 that can be used to inject and modify operation of a corresponding module

In accordance with an embodiment, the components and processes illustrated in FIG. 7, and as further described herein with regard to various other embodiments, can be provided as software or program code executable by a computer system or other type of processing device.

FIG. 8 further illustrates a system for behavior injection in cloud computing platforms or software applications, in accordance with an embodiment.

As illustrated in FIG. 8, in accordance with an embodiment, for each of the tenant-specific GUIDs mapped by the injection service, the injection service can store one or more software objects associated with the behaviors to be injected, such as, in this example, behaviors (objects) 250, 254, 258, for subsequent providing to a requesting module.

In accordance with an embodiment, the system can support a variety of different types of platform code or process and metadata that can be used to inject various types of behaviors into a cloud platform, such as, for example:

Custom class loaders that can be used to run Java code.

Commands or scripts that can be executed on the compute node of the software application platform.

A separate process that can be spawned to perform an activity.

A remote activity that can be performed to change state.

In accordance with an embodiment, the metadata maintained by the injection service can be used to help the cloud software application/platform to understand the steps to apply the new behavior. For example, metadata can be provided as a JSON or XML document listing the steps required to change a corresponding behavior. The platform can then use the received metadata to understand which behavior is required, and then run a corresponding script or code.

In accordance with an embodiment, the injection service can be maintained by the software application/platform provider as a secured service, such that only authorized users can update this service and the mapped information.

In accordance with an embodiment, a cloud software application/platform can interact with the injection service to find a behavior to inject, in a secure manner, for example using HTTPS, a service-service integration, or a client credentials grant.

For example, in accordance with an embodiment, when a particular feature is enabled, say for pre-activation, then the integration platform can run a pre-activation logic, that makes an HTTP request to the injection service, to obtain any corresponding behavior to be injected. The tenant platform is then updated, without requiring patching or an updated to the cloud platform itself.

In accordance with various embodiments, for example an Oracle Integration Cloud, that provide a feature flag service to enable/disable a particular feature for a tenant; the approach described above can utilize the feature flag service to enable behavior injection feature for a particular tenant and a particular lifecycle activity. In such an embodiment, the injection service should be updated with the behavior to be injected before the feature flag is enabled for the tenant.

In accordance with an embodiment, the injection service and API can be provide as a RESTful web service hosted outside of the cloud platform, and the change of behavior of a module/activity within the platform can be performed from outside of the cloud platform via calls to the RESTful web service.

In accordance with an embodiment, to avoid performance issues, a cache of injected behaviors can be maintained, which helps avoid multiple HTTP requests to check behaviors at the injection service at runtime.

For example, in accordance with an embodiment, each lifecycle activity can be associated with two injection points, for example “pre-processing” and “post-processing”. These enable the system to inject behavior before and after the activity respectively. Using an example of an activation process of an integration flow, there can be two injection points for activation—referred to as pre-activation and post-activation.

In this example, if there is an issue with the activation of a flow for a particular tenant, depending upon whether a behavior change is needed before activation or after activation, then a tenant-specific GUID is generated.

For example, in accordance with an embodiment, for pre-activation the tenant-specific GUID can be: <TENANT_ID>_<PRE_ACTIVATION> and for post-activation the tenant-specific GUID can be: <TENANT_ID>_<POST_ACTIVATION>

The GUID is provided to the injection service, and in accordance with an embodiment, if a particular behavior is indicated, then the injection service can return the behavior, for example, as an object, to the requesting module. The cloud platform can then determine, based on the metadata in the object, how to modify the cloud platform for the particular tenant and the particular activity indicated by the GUID, in this instance the activation modules.

FIG. 9 further illustrates a system for behavior injection in cloud computing platforms or software applications, in accordance with an embodiment.

As illustrated in FIG. 9, in accordance with an embodiment, injection points associated with lifecycle activities can be used to check for behaviors to be injected, by checking the injection service using their tenant-specific GUID. In accordance with an embodiment, a request 270 is communicated by the cloud platform on behalf of the tenant platform, including the GUID 272, to the injection service.

When the injection service finds a code/behavior corresponding to the GUID in the request, it provides as a response 280 a software object providing the code/behavior to the requesting module to be executed thereby. For example, the software object can include the platform code or process 282 and metadata 284 specified by the platform provider in configuring that particular GUID in the injection service.

FIG. 10 further illustrates a system for behavior injection in cloud computing platforms or software applications, in accordance with an embodiment.

As illustrated in FIG. 10, in accordance with an embodiment, the system described herein can be used to expose behavioral aspects of the cloud platform or a software application executing therein, so that they can be controlled or modified in a dynamic manner, from outside of the cloud platform, including in this example, for tenant A.

FIG. 11 further illustrates a system for behavior injection in cloud computing platforms or software applications, in accordance with an embodiment.

As illustrated in FIG. 11, in accordance with an embodiment, tenant A can be associated with a plurality of tenant-specific GUIDs including (continuing the example described above) a first GUID A 202 that references injection point (A1) in module A; and a second GUID B 204 that references injection point (B1) in module B—which the injection service has associated with behaviors 250 and 254 respectively. Upon communication of those GUIDs to the injection service, and upon receipt of the software objects from the injection service, those behaviors are injected into the corresponding injection points, for use by tenant A.

FIG. 12 further illustrates a system for behavior injection in cloud computing platforms or software applications, in accordance with an embodiment.

As illustrated in FIG. 12, in accordance with an embodiment that includes for example, an activation module that includes pre-activation and post-activation injection points; and a connection module that includes an injection point; the above-described approach can be used to inject a behavior into the operation of the activation module at its pre-activation injection points, and the connection module, both of which behavior modifications are specific to tenant A. in this example, the platform operations and lifecycle associated with tenant B are not affected.

FIG. 13 further illustrates a system for behavior injection in cloud computing platforms or software applications, in accordance with an embodiment.

As illustrated in FIG. 13, in accordance with an embodiment, in accordance with an embodiment, and the example shown and described above, tenant B can be associated with a plurality of tenant-specific GUIDs including a GUID C 212 that references injection point (A2) in module A—which the injection service has associated with a behavior 258. Upon communication of that GUID to the injection service, and upon receipt of the software objects from the injection service those behaviors are injected into the corresponding injection points.

FIG. 14 further illustrates a system for behavior injection in cloud computing platforms or software applications, in accordance with an embodiment.

As illustrated in FIG. 14, in accordance with an embodiment that includes for example, an activation module that includes pre-activation and post-activation injection points; the above-described approach can be used to inject a behavior into the operation of the activation module at its post-activation injection point, which behavior modification is specific to tenant B. In this example, the platform operations and lifecycle associated with tenant A are not affected.

In accordance with an embodiment, using the above-described approach, the cloud platform can expose behavioral aspects of the cloud platform or a software application executing therein, so that they can be controlled or modified in a dynamic manner, from outside of the cloud platform—including customizing the operation of the platform to address the needs of specific tenant, without affecting operation for other tenants.

Behavior Injection Process

FIG. 15 illustrates a flowchart of a method for behavior injection in cloud computing platforms or software applications, in accordance with an embodiment.

As illustrated in FIG. 15, in accordance with an embodiment, at step 290, a cloud computing environment enables access by tenants to a cloud platform and tenant platform environments associated with the tenants.

At step 291, an injection service enables configuration of software code/behaviors to be injected into cloud platform modules or other components associated with tenants, including mapping, for each of a plurality of tenant-specific globally unique identifiers (GUID) associated with lifecycle activity injection points, a behavior including a platform code or process and metadata that can be used to inject and modify operation of a corresponding module.

At step 292, at a requesting module, one or more injection points associated with lifecycle activities for a particular tenant platform are used to check for behaviors to be injected, by communicating requests to the injection service using tenant-specific GUID(s).

At step 293, the injection service determines availability of behaviors matching the tenant-specific GUID(s), and returns a corresponding platform code or process and metadata for execution by the requesting module.

At step 294, at the cloud platform, the received platform code or process and metadata are used to modify the operation of the requesting module within the particular tenant platform environment.
